I have an 2000 isuzu amigo 3.2 v6 RWD I had just got a new ECM installed and now when I have the a/c on the car will die immediately when I put it into drive, it runs great when the a/c isn't on and it idles good with the A/C on and it's fine when I'm at highway speeds it's just when I'm sitting or at low speeds, any ideas?

Is the replacement ECM/PCM actually a new reprogrammed module OR a remanufactured module OR from the junk yard?

Does your truck have a manual 5 speed transmission or an automatic transmission?

Is the Check Engine Lamp (CEL) illuminated?

Do the gear selected lamps on the Instrument Panel match the position of the shift lever?
Does the engine stall when Drive is selected or when you take your foot Off the Brake Pedal after Drive has been selected.
Does the engine stall if Reverse is selected?

The gears match and it stalls the instant you pull it out of park
